1) You can toast half of the coconut (about 2 cups) in a 350 degree oven for about 12-15 minutes by stirring occasionally but keeping a close eye to ensure if does not burn. Just be sure the spread the coconut flakes on a line sheet pan, evenly.
2) I did mine stove top in a stainless pan on medium heat, stirring often.
3) Once toasted, add the toasted and non-toasted coconut to a food processor and process for approximately 7-10 minutes until the coconut turns into butter.

Store in a glass jar. The butter will harden under cooler temperatures or if you store in the fridge. You can simply warm the jar in hot water. I store mine in a cool, dark shelf.
